The embodiment of the disclosure relates to the technical field of risk control, in particular to a drowning risk control method and device and a vehicle.
Background
When the temperature drops below a certain temperature, the surfaces of water systems such as rivers and lakes can be naturally frozen to form ice layers. When the ice layer reaches a certain thickness, the ice layer has a certain bearing capacity, and vehicles, pedestrians and the like can pass through the ice layer as a temporary road.
The bearing capacity of the ice layer is greatly influenced by natural environment, for example, factors such as water temperature, air temperature, local water flow velocity at the lower part of the ice layer, vortex flow under the ice layer and the like can cause the ice layer to become thin, and the bearing capacity of the ice layer is influenced. At present, when vehicles, pedestrians and the like pass through an ice layer, a passing route is selected on the ice layer completely depending on the prior passing experience. If the bearing capacity of the ice layer on the traffic route is poor, the ice layer is likely to collapse, the risk of falling into water of vehicles, pedestrians and the like is great, and casualties and economic loss are caused to happen occasionally. In summary, it is an urgent need to solve the problem of reducing the risk of vehicles, pedestrians falling into water when the vehicles, pedestrians, etc. move on the ice layer.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In a first aspect, an embodiment of the present disclosure provides a method for controlling a risk of overboard, where as shown in fig. 1, the method mainly includes:
101. when the target object moves on the ice layer, the thickness and the water depth of the ice layer corresponding to the current position of the target object are obtained.
The target object described in this embodiment relates to the scenario in which the method is applied. Optionally, the target object may include, but is not limited to, any one of the following: automotive, non-automotive, human, animal, mobile toy. For example, when people need to pass through an ice layer by means of a vehicle, the target object can be a motor vehicle such as an electric automobile, a fuel automobile, a hybrid automobile, an electric motorcycle, an electric bicycle and the like, and can also be a non-motor vehicle such as a bicycle, an ice vehicle and the like; when a person passes through the ice surface without the aid of a vehicle, the target object is a person. When one desires an animal to pass through the ice surface, the target object is an animal. When people need to use a small toy car to transport objects such as express delivery and the like on the ice surface, the target object is a movable toy.
In this embodiment, in order to timely know whether the target object has a risk of falling into water, when the target object moves on an ice layer, the thickness of the ice layer and the depth of water corresponding to the current position of the target object need to be timely obtained along with the movement of the target object, so that the risk of falling into water is determined by using the obtained thickness of the ice layer and the obtained depth of water. How to timely acquire the thickness and the depth of water of the ice layer corresponding to the current position of the target object is described below, where the timely acquisition mode at least includes the following two types:
first, when a target object moves on an ice layer, the thickness and the depth of the ice layer corresponding to the current position of the target object are acquired in a set period.
In this way, when the target object moves on the ice layer, the thickness and depth of the ice layer corresponding to the current position of the target object are always acquired in a fixed set period.
Specifically, the time duration of the set period needs to comprehensively consider the timeliness of the drowning risk determination and the calculation force requirement of the drowning risk determination. For example, if it is required to determine whether the target object has a risk of falling into water in time, the time of the set period may be short, for example, 1 second. For example, if the computational effort required for the determination of the risk of overboard is reduced, the set period is longer, for example, 5 seconds.
For example, if the set period is 2 seconds, the ice layer thickness and the water depth corresponding to the current position of the target object are acquired every 2 seconds.
Secondly, acquiring the thickness and the water depth of an ice layer corresponding to the current position of the target object in a set first cycle; and if the thickness of the ice layer acquired in the adjacent N periods is smaller than a preset thickness threshold value and/or the water depth is larger than a preset second water depth threshold value, acquiring the thickness and the water depth of the ice layer corresponding to the current position of the target object in a set second period, wherein the second period is smaller than the first period, and N is larger than or equal to 1.
In this manner, the period for acquiring the thickness of the ice layer and the depth of water corresponding to the current position of the target object is not constant when the target object moves on the ice layer, but when the risk of falling into water increases, the period for acquiring the thickness of the ice layer and the depth of water is adjusted so as to increase the frequency of determining the risk of falling into water when the risk of falling into water increases.
Specifically, if the thickness of the ice layer acquired in the N adjacent periods is smaller than a preset thickness threshold value and/or the water depth is larger than a preset second water depth threshold value, it indicates that the bearing capacity of the ice layer is not good enough and/or the degree of danger of the target object falling into water is increased. In order to timely determine the risk of falling into water of the target object, a second period with shorter duration is adopted, and the period of the thickness of the ice layer and the depth of water corresponding to the current position of the target object is continuously obtained so as to timely determine the risk of falling into water, thereby reducing the risk of falling into water of the target object.
For example, when the vehicle travels on an ice layer, the thickness of the ice layer and the depth of water corresponding to the current position of the vehicle are acquired in a first period of "5 seconds" as the vehicle travels. And after the first period and the second first period are determined, the thickness of the ice layer obtained is smaller than 20 cm, and the water depth is larger than 8 m, starting from the third period, and obtaining the thickness of the ice layer and the water depth corresponding to the current position of the vehicle in the second period of 1 second.
In this embodiment, the following describes the thickness and the depth of water of the ice layer corresponding to the current position of the target object, and the thickness and the depth of water of the ice layer corresponding to the current position of the target object have at least two forms:
first, the thickness of the ice layer and the water depth corresponding to the current position of the target object are the thickness of the ice layer and the water depth at the current position of the target object.
When the target object moves on the ice layer, the target object has contact points that are in direct contact with the ice surface, and these contact points are usually the acting points of the target object on the ice layer. The area range corresponding to each acting point of the target object is the current position of the target object.
For example, as shown in fig. 2, the target object is a vehicle, the wheel is an acting point, and the thickness of the ice layer and the depth of water corresponding to the current location of the target object are the thickness of the ice layer and the depth of water corresponding to the current location "a" of the target object, where a position a of the target object is located between two thick dotted lines in fig. 2, and the position a includes the acting point of the wheel.
Secondly, determining the position to which the target object is to move according to the current position of the target object. The ice layer thickness and the water depth corresponding to the current position of the target object are the ice layer thickness and the water depth at the position to which the target object is to be moved. It should be noted that, since the thickness of the ice layer and the water depth correspond to the position to which the target object is to be moved, when it is determined that there is a risk of falling into water at the position to which the target object is to be moved based on the thickness of the ice layer and the water depth, the target object can be prevented from moving to the position in time, and thus the risk of falling into water of the target object is reduced.
Note that, the positions to which the target object is to be moved include two types: one is that the area ranges corresponding to the positions to which all the points of force of the target object are to be moved are the positions to which the target object is to be moved. For example, the target object is a vehicle, the force application points of the vehicle are four wheels, and the area range corresponding to the position to which the four wheels are to move is the position to which the target object is to move. The other is that the area range corresponding to the position to which the target object part is to be moved is the position to which the target object is to be moved. For example, the target object is a vehicle, the force application point of the vehicle is four wheels, and since two rear wheels will move to the position where two front wheels move, and the position where the front wheels move must have been subjected to the drowning risk determination, only the area range corresponding to the position where two front wheels are to move is determined as the position where the target object is to move.
For example, as shown in fig. 2, the target object is a vehicle, the current position of the target object is a, the position to which the target object is to be moved is determined as a position B according to the position a (in fig. 2, the position B to which the target object is to be moved is defined as an area range corresponding to positions to which four wheels of the vehicle are to be moved), and the thickness of the ice layer and the depth of water corresponding to the thickness of the ice layer and the depth of water at the position B to which the vehicle is to be moved are determined as the thickness of the ice layer and the depth of water corresponding to the current position a of the vehicle.
In this embodiment, the process of obtaining the thickness of the ice layer and the depth of water corresponding to the current position of the target object includes the following steps:
step one, obtaining at least one ice layer thickness and at least one water depth corresponding to an ice layer corresponding to the current position of a target object.
Specifically, the acquisition process of this step includes the following two methods: the method comprises the steps of firstly, obtaining at least one ice layer thickness and at least one water depth corresponding to an ice layer at the current position of a target object. Secondly, determining the position to which the target object is to move according to the current position of the target object; and acquiring at least one ice layer thickness and at least one water depth corresponding to the ice layer at the position to which the target object is to move.
Specifically, the thickness of the ice layer can be obtained through an ice layer sensor, and the water depth can be obtained through a water depth detector. For example, corresponding water depth detectors and corresponding ice layer sensors are arranged at corresponding positions of four wheels of the vehicle, and the water depth and the ice layer thickness of the four wheels are obtained through the water depth detectors and the ice layer sensors respectively.
For example, a water depth detector and an ice layer sensor are installed in front of the vehicle and correspond to the position to which the vehicle is to be moved, and the water depth and the ice layer thickness at the position to which the four wheels are to be moved are respectively obtained through the water depth detector and the ice layer sensor.
When the target object moves on the ice layer, the target object has contact points that are in direct contact with the ice surface, and these contact points are usually the acting points of the target object on the ice layer. The ice layer thickness and the water depth of the acting point directly influence the risk of falling into water of the target object, and therefore the at least one collected ice layer thickness and the at least one collected water depth should correspond to the acting point.
And step two, determining the minimum ice layer thickness in the at least one ice layer thickness as the ice layer thickness corresponding to the current position of the target object, and determining the maximum water depth in the at least one water depth as the water depth corresponding to the current position of the target object.
Specifically, the smaller the ice layer thickness is, the greater the risk of falling into water of the target object is, so that the minimum ice layer thickness is selected as the ice layer thickness corresponding to the current position of the target object. The larger the water depth is, the greater the probability of life danger or property loss after the target object falls into water is, so that the maximum water depth is selected to be the water depth corresponding to the current position of the target object.
102. Judging whether the target object has a water falling risk or not according to the thickness of the ice layer and the water depth, and if the target object has the water falling risk, executing 103; if the target object does not have the risk of falling into water, the process continues to be executed 101 as the target object moves on the ice layer.
In this embodiment, the method for determining whether the target object has the risk of falling into water according to the thickness of the ice layer and the water depth includes at least the following two methods:
firstly, judging whether the water depth is greater than a preset first water depth threshold value; if the water depth is larger than a first water depth threshold value, continuously judging whether the ice layer with the ice layer thickness can bear the target object; and if the ice layer with the ice layer thickness cannot bear the target object, determining that the target object has a water falling risk.
Specifically, when the water depth is determined to be not greater than the first water depth threshold, it is determined that the target object does not have a risk of life or property loss even if the target object wades in the water, it is determined that the target object does not have a risk of falling into the water, and the execution 101 continues to acquire the thickness of the ice layer and the water depth corresponding to the current position of the target object as the target object moves on the ice layer.
Specifically, when it is determined that the water depth is greater than the first water depth threshold, it is determined that the target object wades, and if the target object has a risk of life risk or property loss, it is necessary to continuously determine whether the ice layer with the ice layer thickness can bear the target object. If the ice layer with the ice layer thickness is determined to be capable of bearing the target object, it is indicated that the ice layer is capable of bearing the target object, and the target object does not have a risk of falling into water, 101 is executed to continue to acquire the ice layer thickness and the water depth corresponding to the current position of the target object. If it is determined that the target object cannot be carried by the ice layer with the ice layer thickness, it is determined that the target object has a risk of falling into water, and 103 is required to execute emergency treatment actions corresponding to the ice layer thickness and the water depth on the target object, so that life risks or property losses of the target object caused by falling into water are avoided.
Specifically, the following describes a process of determining whether an ice layer with an ice layer thickness can bear a target object, where determining whether the ice layer with the ice layer thickness can bear the target object includes the following steps:
step one, determining the carrying capacity of the ice layer with the ice layer thickness and determining the carrying capacity of the target object.
Specifically, the supportable capacity of the ice layer can be characterized by any one of the following parameters: pressure, mass, gravity. Accordingly, the load capacity of the target object can also be characterized by any one of the following parameters: pressure, mass, gravity. It should be noted that the parameters used for the carrying capacity of the ice layer and the carrying capacity of the target object are the same. Illustratively, the bearable capacity of the ice layer and the load capacity of the target object are both characterized using pressure.
Specifically, the method for determining the carrying capacity of the ice layer with the ice layer thickness comprises the following steps: and determining the bearable capacity of the ice layer with the ice layer thickness by inquiring the corresponding relation table of the ice layer thickness and the bearable capacity. The corresponding relation table of the ice layer thickness and the bearing capacity is obtained through experimental calibration. Illustratively, the correspondence table of the ice layer thickness and the bearable capacity is a pressure basis table obtained by sequentially performing sectional calculation on the ice layer thickness of 10 cm, and the table includes: the pressure corresponding to the thickness of the ice layer of 10 cm and below is 10 kilopascals, the pressure corresponding to the thickness of the ice layer of 10 cm-20 cm is 20 kilopascals, and the pressure corresponding to the thickness of the ice layer of 20 cm-30 cm is 30 kilopascals. And acquiring the thickness of an ice layer corresponding to the current position of the target object as 15 cm, and determining that the carrying capacity of the ice layer with the ice layer thickness of 15 cm is 20 kilopascals.
Specifically, the method for determining the load capacity of the target object includes the following two methods: first, the load amount of the target object is determined based on the own weight of the target object and the maximum load weight of the target object. For example, the target object is a vehicle, and the load amount of the vehicle is determined to be "18.9 kpa" according to the sum of the own weight of the vehicle and the maximum load weight and the contact area of the tires of the vehicle with the ice layer. Secondly, the load capacity of the target object is determined based on the self weight of the target object and the current load weight of the target object.
And step two, determining a bearable quantity threshold corresponding to the ice layer according to the load quantity of the target object.
Specifically, the method for determining the bearable capacity threshold of the ice layer object comprises the following two steps: firstly, the sum of the load capacity of the target object and the preset load capacity is determined as the bearable capacity threshold. Secondly, determining a load coefficient according to the current environment temperature and/or the heat generated by the target object when the target object moves, wherein the load coefficient is greater than or equal to 1; and determining the product of the load coefficient and the load capacity of the target object as the bearable capacity threshold. Specifically, since the ambient temperature and the heat generated by the target object during movement can both melt the ice layer and reduce the carrying capacity of the ice layer, the influence of these temperatures on the ice layer needs to be considered, so that the load factor is selected to determine the threshold of the carrying capacity. Specifically, the determination of the load coefficient may be determined by querying a preset ambient temperature and/or a correspondence table between the heat and the load coefficient.
And step three, judging whether the bearable quantity is smaller than the bearable quantity threshold value.
Specifically, the threshold of the supportable capacity is a necessary condition that the target object safely passes through the ice layer, and only when the supportable capacity of the ice layer corresponding to the current position of the target object is greater than the threshold of the supportable capacity, it is indicated that the target object can safely pass through the ice layer, so that it is necessary to determine whether the supportable capacity is less than the threshold of the supportable capacity.
And step four, if the bearable quantity is smaller than the bearable quantity threshold value, determining that the target object has the risk of falling into water.
Specifically, if the bearable amount is smaller than the bearable amount threshold, it is determined that the target object cannot be borne by the ice layer, and it is determined that the target object has a water falling risk.
And fifthly, if the bearable quantity is not smaller than the bearable quantity threshold, determining that the target object does not have the risk of falling into water.
Specifically, if the bearable amount is not less than the bearable amount threshold, it is determined that the target object can be borne by the ice layer, and the target object can safely pass through the ice layer, so that the target object is determined not to have the risk of falling into water.
Secondly, determining risk thresholds according to the corresponding relation between the water depth and preset thresholds, wherein the corresponding relation between the thresholds is the corresponding relation between a plurality of water depths and a plurality of risk thresholds, and each risk threshold is determined based on the corresponding water depth and the load capacity of the target object; judging whether the ratio of the thickness of the ice layer to the depth of water is greater than a risk threshold value; and if the ratio is not greater than the risk threshold, determining that the target object has the overboard risk.
Specifically, the threshold value corresponding relation is calibrated in advance based on the water depth and the load capacity of the target object. Since the load amount of the target object is used when the threshold correspondence relationship is calibrated, different target objects have different threshold correspondence systems. In addition, the load capacity of the target object is the maximum load capacity of the target object, for example, the load capacity of the target object is the sum of the self load capacity of the target object and the maximum load capacity of the target object.
In particular, the risk threshold value characterizes a degree of risk of the target object to be at risk of falling into water on an ice layer having a corresponding water depth and ice layer thickness. The threshold value correspondence may be a case where a plurality of different water depths correspond to the same risk threshold value, that is, one water depth interval corresponds to one risk threshold value.
